SIMULATION / SA-PROC-CMP-001

CMP pattern-density dishing and erosion replay
CMP Dishing

Replay pattern density, feature width, overpolish proxy, and pad age to connect layout density with dishing, erosion, nonuniformity, and planarization evidence.

EXPLORE

Start with the observable.

Use this page when the simulation is the primary artifact. The linked lesson explains the concept; the linked lab keeps the visual replay surface available.

guided exploration
  • Connect layout density to wafer topography before treating CMP as a blanket removal rate.
  • Read dishing and erosion separately because they describe different geometry failures.
  • Use dummy-fill and metrology vocabulary without exposing slurry, pad, or endpoint recipes.

RUN CARD

Conditions before conclusions.

This page replays saved CMP Dishing rows and does not run a live solver, upload workflow, proprietary model, process recipe, or signoff flow.

METHODS

How the number was made.

Methods are written for citation discipline: the extraction rule matters as much as the plotted value.

method

Dishing proxy increases with feature width, overpolish, pad factor, and low-density exposure.

Keep this method attached when reusing the figure or metric.

method

Erosion proxy increases with dense pattern area and overpolish pressure.

Keep this method attached when reusing the figure or metric.

method

Planarization score combines residual topography and removal nonuniformity penalties.

Keep this method attached when reusing the figure or metric.

LIMITS

What this page does not claim.

The MVP is useful because the limits are visible. These statements prevent a teaching simulation from being cited as silicon evidence.

non-claim

No slurry chemistry, pad conditioning, pressure map, endpoint sensor, material stack, or recipe setting is modeled.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

Pattern density is normalized and not tied to a product layout.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

Use this page for process/layout literacy, not CMP process development or qualification.

Carry this boundary into any derivative note, paper draft, or slide.

EVIDENCE

Trace the claim back to artifacts.

The evidence route remains the catalog-level browser; this page is the simulation-level reading card.

evidence note

The public JSON stores every density, width, overpolish, pad-age, dishing, erosion, and score row.

SA-PROC-CMP-001

evidence note

The CSV export gives process learners a safe table for dummy-fill and metrology discussion.

SA-PROC-CMP-001

evidence note

The card links process fundamentals with layout-density consequences in the domain browser.

Source spine

These links anchor the public teaching model. They do not convert the replay into a qualified process recipe or signoff result.

Public execution boundary

No server-side live ngspice execution, uploads, accounts, payments, comments, newsletter signup, or job/event submissions are active on this page.
